Find LCM of 868,825,558,452 with Prime Factorization
| 2 | 868, 825, 558, 452 |
| 2 | 434, 825, 279, 226 |
| 3 | 217, 825, 279, 113 |
| 31 | 217, 275, 93, 113 |
| 7, 275, 3, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 31 x 7 x 275 x 3 x 113 = 242757900
Therefore, the lowest common multiple of 868,825,558,452 is 242757900.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
868 x 825 x 558 x 452 = 180611877600
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
452 : 1, 2, 4, 113, 226, 452
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,825,558,452, is 1.
Now, the common factors can be found like this.
868:2x 2x 7x 31
825:3x 5x 5x 11
558:2x 3x 3x 31
452:2x 2x 113
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 31 = 744
Therefore, the value for common factors is 744.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 180611877600/(1x744)
LCM = 180611877600/744
LCM = 242757900
Thus, we can understand that the LCM of 868,825,558,452 is 242757900.
